Looking for an easy — and visually enticing — way to share 3D results plots from the COMSOL Multiphysics® software? In this blog post, we demonstrate how to export your 3D plots as glTF™ files and share them in a variety of web-based graphics viewers, and even in Facebook® posts.

If you want to create an animation from your simulation results, the COMSOL Multiphysics® software offers a variety of powerful and flexible options. In this blog post, we will explore the idea of creating a nontrivial animation by combining slices along the azimuthal direction for a 3D model.

Have you ever tried to plot multiple quantities on one graph, only to realize that the scales don’t match up? You can solve this problem by adding a second y-axis to your 1D plot to include two scales of values. In the video below, we introduce a case where you would want two y-axes. We then show you how to add a second y-axis to your graph and create helpful annotations in the COMSOL Multiphysics® software.

If you’re looking for ways to manage multiple solutions, version 5.3 of the COMSOL Multiphysics® software offers several new tools for doing so. These include options for combining two solutions into one; storing solutions in different data sets so that they can be postprocessed and analyzed individually; and joining solutions to, for example, compare them. In this blog post, we will look at how to use these new tools.

Have you ever wanted to query the results of your model within an arbitrary geometric subregion? You might think that this requires adding geometries to a model and recomputing the solution. Instead, in the COMSOL Multiphysics® software, we can just add and reposition a part solely for the purpose of evaluating the results. We will demonstrate this in the context of computing mutual inductance between coils and discuss simpler techniques that can be used for a reduced set of cases.

If you’ve read the COMSOL Blog before, you might know that we like to include animations in our blog posts to help illustrate concepts more clearly. Most of these animations are exported directly from the COMSOL Multiphysics® software, which means that you can export animations for your own simulations, too. At the bottom of this post, we link to a video to show you how to do that.

When looking through scientific papers, it’s common to see colorful results. Although aesthetically pleasing to some, these results can be difficult to interpret for engineers with color vision deficiency (CVD). You may think that presenting results in grayscale could help, but humans are less able to discern between different shades of gray. So what’s the best option here?

You can generate and visualize randomized material data with specified statistical properties determined by a spectral density distribution by using the tools available under the Results node in the COMSOL Multiphysics® software. In this blog post, we show examples that are quite general and have potential uses in many application areas, including heat transfer, structural mechanics, subsurface flow, and more.

When your simulations consume significant memory, do you buy a bigger computer? When they take too long to solve, do you just run them overnight? Often, you don’t have another option. But sometimes, if you have the right tools, you can find a better approach by exploiting the mathematical structure. Today, we will show you how to use the so-called maximum principles to save computational resources and time in the COMSOL Multiphysics® software.

Have you ever modeled deforming objects in the COMSOL Multiphysics® software and wanted to know the distance between them? In today’s blog post, we will look at how to compute distances between objects using methods for determining the closest distance field. We’ll also find out how to use the distance field as a part of a multiphysics model.

You’ve generated your simulation results and you want to communicate your findings with other people. To do so clearly and effectively, you will need to create easy-to-understand, eye-catching visualizations. Therefore, as of COMSOL Multiphysics® software version 5.2a, you now have six new color tables to further enhance your postprocessing. Let’s learn about the inspiration behind these color tables and take a look at a few specific use cases.
